Both batteries are the same size, but I am intending on starting on the main battery only. My alternator-out load analysis shows around 17 amps to keep it in the air, though I think I can drop that to 10. The "keep the engine running" components may run off either bus, but the endurance bus is just connected to the main. Could I install a crossfeed switch between the main and engine batteries, without a contactor? It would allow me to use the engine battery for the endurance bus, to supplement the main battery. That would also allow me to simultaneously charge both batteries without engaging the engine battery contactor. I'll try and attach a pdf. BTW, after a year and a half, I am somewhat back in the air, though many bugs remain.

Cheers Alan [610xl builder >almost ready to start taxi run testing] After reading through the available installation data on the Icom IC-A210 I've discovered that the 210 is a head-n-shoulders upgrade from the 200. Most noteworthy are extensive audio management features with functions and gains set by software using a front panel menu system. Another interesting feature is what appears to be rear connector plate options. The stock input/output connector plate works with the same Molex wires-to- ecb style of harnes connector . . . same as the A200. The A210 install kit comes with an "MB-113" adapter module to convert the legacy molex connnector interface Emacs! To the more robust Dsub 15 connector. Emacs! If we look at the A210 installation data . . . http://tinyurl.com/nxw5jm . . . we see that half of the 30 wires available in the Molex pin-out are available in Dsub pinout and in different combinations. For example, only 2 of the 6 power/gnd connections are available in the Dsub. The Molex doesn't offer the RS232 GPS interface option. The Molex connection offers 3 aux audio inputs, the Dsub offers only one. Certainly, the Dsub pinouts offer enough features to accomplish a perfectly useful installation in an airplane. Getting back to the intercom issue, we see that there's a raft of menu driven audio performance setup features. Further, pin 10 (intercom enable) in the Molex connector does not appear on the Dsub connector. Admittedly, with out a schematic of the MB-113 adapter, we don't know if Molex 10 is simply ignored or is tied to ground by the adapter. Further, functionality of the intercom ground to activate connection is not explained. It's illustrated in the Molex wiring as a useful thing to attache to an intercom PTT button, but in the user's manual . . . http://tinyurl.com/nsvye4 the use of this push button is not explained. However, on the description of panel controls we see that item (1) DUAL SWITCH has a time-based function (hold for 2+ seconds) to turn the intercom function ON or OFF. It would be nice if the manuals were more complete in this regard. I'll keep an eye open for the service manual on this radio. Schematics are VERY useful in figuring out how things work. Does anyone on the List have an A210 installed and working who can help Alan sort through this radio's intercom functionality?

It was a bit of nightmare; I couldn't get the two systems working- the headphones worked fine but the mic circuits wouldn't work properly (I am still busy with that project). Recently I had to install the PM1000II on the Sling (that little aircraft that is making its way between the Virgin Islands and Florida as I write!) where it interfaced to a Garmin SL30 nav/ comm radio. This time I called PS themselves and checked up on a few things. One of the things that I discovered was that one must not put an 'aux PTT' in the same way that they call for 'aux mic and phone jacks'. I have yet to test the A210/ PM1000 system after removing this item but I can tell you that the SL30/ PM1000 combination worked just fine when I left the 'aux PTT' out- so perhaps that's one of the problems? As a matter of interest, PS Eng told me that the PTT's are hard wired through so that, even if (in the unlikely event of failure, ladies and gentleman.) there is a failure with PM1000 the PTT's will still work.

Might look at putting a intercom in.
